I am using AE CS6 and lately have not been able to save my workspace. After telling it to save, I receive the error: "After Effects error: Unexpected data type". My previously saved workspaces are now missing too.

My workspace looks like this but with another comp window on the right screen. At first I thought it was because that comp screen was locked but I unlocked it and tried again with no success. Also, why would my older workspaces have disappeared?? Curious.

Any help would be great. It's a pain in the bum having to set it up every time.
